Diagnosing problems
If you experience problems with your computer, use the Lenovo Solution Center program as a starting point for solving them.
The Lenovo Solution Center program enables you to troubleshoot and resolve computer problems. It combines diagnostic tests, system information collection, security status, and support information, along with hints and tips for maximum system performance.
Notes:
•The Lenovo Solution Center program is available only on models preinstalled with the Windows 7 operating system. It also can be downloaded from http://www.lenovo.com/diagnose.
•If you are using other Windows operating system rather than Windows 7, go to http://www.lenovo.com/diagnose for the latest information on diagnostics for your computer.
When you are setting up your computer, the Lenovo Solution Center program prompts you to create recovery media, which you can use to restore the hard disk drive to the factory default state. For more information, see “Creating and using a recovery media” on page 57.
To run the Lenovo Solution Center program on the Windows 7 operating system, see “Accessing ThinkVantage programs on the Windows 7 operating system” on page 13.
For additional information, refer to the Lenovo Solution Center help system.
Note: If you are unable to isolate and repair the problem yourself after running the program, save and print the log files created by the program. You will need the log files when you speak to a Lenovo technical support representative.
Troubleshooting
If your computer has an error, it typically displays a message or an error code, or a beep sounds when you turn it on. When you experience a problem, refer to the corresponding sections in this topic to try to solve the problem by yourself.
